Inhalation of benzene is associated with increased risk of leukemia. Edmonton Indoor Air Quality Study (EIAQS) investigated what factors were related to higher or lower levels of benzene in Edmonton homes. Factors examined were: season (winter, summer), environment (indoor, outdoor), traffic volume, proximity to downtown, socioeconomic status, garage type, number of occupants, and air exchange rate/age strata.
Neighborhoods were age stratified and ten dwellings were randomly sampled from each stratum. Fifty dwellings were sampled with SUMMA™ canisters for 7 consecutive 24-hour periods in winter and summer of 2010. Benzene samples were analyzed by GC/MS. Data on daily activity patterns and house characteristics were collected using questionnaires and analyzed using SAS v9.2.
A stepwise selection regression model predicted that 28% of the indoor benzene variability can be explained by season and presence of attached garage with connecting door as significant predictors (p<0.05).
